Treatment of sandwich-type mixed (phthalocyaninato)( porphyrinato) metal complex [HEu(III){Pc(alpha-3-OC(5)H(11))(4)}{TriBPP( NH(2))}] (3) [Pc(alpha-3-OC(5)H(11))(4)=1,8,15,22-tetrakis(3-Pentyloxy)-phthalocyanin ate, TriBPP(NH(2))=5,10,15-tris(4-tert-butylphenyl)-20-(4-aminophenyl)porphyr inate] with N-n-butyl-1,6,7,12-tetra(4-rert-butylphenoxyl)perylene-3,4-dicarboxylate anhydride-9,10-dicarboxylate imide (2) in the presence of imidazole in toluene afforded the novel perylene diimide-appended mixed (phthalocyaninato)(porphyrinato) europium(III) double-decker complex (5). Porphyrin-PDI dyad 4 was also obtained by similar method. The electronic absorption spectroscopic and electrochemical properties of PDI-appended double-decker sand the model compounds 2, 3, and 4 were studied, the results indicated that there was no considerable ground-state interaction between the double-decker unit and the PDI unit in 5. The fluorescence measurements revealed that the emission of PDI unit was effectively quenched by the double-decker unit, suggesting remarkable intramolecular interaction in 5 under excited state.
